sonims. craze-41) ,This invention-relates to devices for puncturing'andforming'a pouring opening in the wall of a cardboard or the likecontainer. Devices designed for the purpose of insertion into a wall ofa cardboard container in order to form an opening and/or spout for thedispensing of materials from the, container are well known.-

It is the primary object of my inventionto provide a new and improvedpuncturing and dis-;

pensing device particularly designed 'to be used and which may bequickly attached'to the con- 3 tainer ,or' detachedftherefrom.

the provicontainer. V

Another object is the provision of an improved device of the kinddescribed which has no porcontainer and remains hinged at its top totheedge ofthe top wall I3, is clamped'between the with a cardboard'orthe like containenwhich is easily and'che'aply made, ofsimpleuconstruction,

thus protruding from the container either during use or when not in use.

It is another objectto provide a flat metallic container and one form ofthe invention applied thereto and ready'for use in dispensing materialsuch as soap powder from the container;

Figure 5 is a front elevation of the device of I Figure 2 as seen fromthe right of Figure 2; and

Figure 6 is a plan view of a metal blank which, when properly folded,forms the device of Figure 2.

As shown in Figure 1, the device generally designated at I I3 has beeninserted through a side wall II of a cardboard container I2 and adjacentthe top wall I3 thereof so that an opening I! is provided in the sidewall n, the top of the opening-being adjacentthe top. wall n. The

device itself. in the illustrated embodiment, is formed from a flatblank I5 shown in Figure 6.

A large rectangular flap or guide I6 overlies the top wall I3. The wallI3; plus a flap I'I- (Fig. 4).

which has been cut from' the side wall II of the flap or guide I6 and aledge I8 which is a continuation of the flap I8. As is apparent fromFigures 2, 4 and 6, the ledge I8 is parallel to and slightly spaced fromthe flap I6, being formed by bending the blank substantially at theportion indicated by the dotted line I9 of Figure 6.

A pair of opposed and inwardly inclining side walls 20 and M extenddownwardly from the ledge I8 and term nate in a pair of inwardlyextending pointed flaps 22 and 23 which lie in a plane substantiallyparallel to the ledge I8 and flap or guide I6. The side walls 28 and 2Iare formed by bending the blank substantially at the portions indicatedby the dotted lines 24 and 25 of Figure 6, and the pointed flaps 22 and23 are properly located with respect to the side walls 20 and 2I and theledge I8 by bending the blank substantially at the portions indicated bythe dotted lines 26 and 21 of Figure 6.

The longer sides 28 and 29' of the pointed flaps 22 and 23 abut againsteach other as best shown in Figure 3 and provide a pointed cutting knifeparallel to the flap or guide I6 and pointing in the same direction,away from the line where the flap I6 joins the ledge I8.

A flap 28, which is of substantially triangular shape as shown in Figure6, extends downwardly from the ledge I8 and forwardly toward the cuttingknife as best shown in Figures 2 and 4. The

flap 28 is properly located by bending the blank I5 substantially alongthe portion indicated by, 40

the dotted line 29 of Figure 6, which is preferably curved asillustrated in Figures 2 and 4 to facilitate forcing hinged flap IIupwardly during "insertion of the spout. The lowermost or free end ofthe'fiap 28 extends substantially to the top of the cutting knife, asshown in Figures 2, 4 and 5. The purpose of the flap 28 is to force thehinged flap II upward as the device is inserted into the carton, so thathinged flap I1 will be movedup out of the way and between the ledge I8and flap II'i as shown in Figure 4. Since it is not the purpose of theflap 28 to obstruct the passage of thematerial being dispensed from thebox, it does not necessarily fill or block the tubular passage formedbythe ledge I8, side walls 28 and 2I, and the pointed flaps 22 and 23.

While the material could be dispensed sold! through the aforementionedtubular passage, the walls of the passage would block entrance thereuntoexcept from its end adjacent the cuttint knife. Accordingly, an aperture33 (Fig. l) ls formed through the walls or the said passage adjacent thepierced side wall ll of the box by the expedient of cutting away aportion of each pointed flap 22 and 23 at the ends thereof which areremote from the cutting mife. Thus, a passageway or spout for thematerial in the box is formed by the rear edges of the point d flaps 22and 23, a portion of the bottom edges 01 the side walls 20 and 2 I, andthe bottom edge of the opening formed in the side wall H of thecontainer 42 by the insertion of the device III.

In order to insert the device into the container, it is placed on theside of the container with the flap or guide It resting flatly on thecontainer top wall i3 and with the point of the cutting knife restingagainst the outsid surface of the side wall H. While holding the flap orguide It against the top of the container, the device is pushed parallelto wall so that the cutting knife pierces the wall II and the wholedevice is pushed further until it has been insertedwholly into thcontainer as shown in Figure 1. It will be frictionally held in thecontainer by the top i3 and the flap I! which are engaged between thetop of the ledge t8 and the bottom of the flap or guide IS. The distanceto which the device can be inserted is limited by the engagement of theedge of the top l3 with the fold in the device where the guide l6 joinsthe ledge It, as most clearly shown in Figure 4. The dimensions of thedevice are such that, when it has been fully inserted, th rear portionsof the side walls 20 and 2| bear against the sides of the opening llformed in the side wall of the container, and prevent the leakage ofmaterial from the container between the wall ll of the container and theside walls 20 and 2| of the device.

It will be observed that the forward and inclined edges of the sidewalls 20 and 2!, as well as the forward and inclined edges of thepointed flaps 22 and 23, are sharpened to form knife edges 3| and 32 asshown in Figure 6, so that as the device is inserted into the containerthe forward edges of the side walls, as well as the forward edges of thepointed flaps, perform a cutting operation to provide th opening throughwhich the device is inserted into the container.

While the illustrated embodiment of the device is shown made from ablank out from sheet metal or the like, it is to be understood that itmay be formed in other ways as by casting or molding, and that it neednot b made of metal but can be made of a plastic material, since theplastic materials are sufliciently hard to be used for cutting throughthe average cardboard container.

The invention may be embodied in other speciflc forms without departingfrom the spirit or essential characteristics thereof. The presentembodiment is therefore to be considered in all respects as illustrativeand not restrictive, the scope of th invention being indicated by theappended claims rather than by the foregoing description, and allchanges which come within the meaning and range of equivalency of theclaims are therefore intended to be embraced therein.
